i Claims.

rIhis invention relates to a mop and more Aparticularly to the head and handle socket and their pivotal connection.

The instant structure lis an improvement `of that disclosed in Letters Patent 1,912,632, issued to John Glover on June-6, 1933, andthe prime object is to provide a mop wherein the head and handle socket may be vmade entirely from sheet metal with a more eihcient pivotal connection or hinge joint and in a less number of parts.

I especially aim to overcome the additional expense and labor incident to employing a separate pintle for the pivotal connection or hinge and the use of a fastening to maintain the socket in shape and engaged with the pintle.

Another object is to provide a handle socket With which the pintle is in a novel manner in tegrally formed and a head having novel means mounting the pintle and including a displaceable part to enable attachment of the pintle thereto.

The more specific objects and advantages will become apparent from a `consideration of the description following, taken in connection with the accompanying drawing illustrating one operative embodiment, by way of example:

In the drawing,

Figure 1 is a plan View of a connected mop head and handle socket, according to my invention;

Figure 2 is a central longitudinal vertical sec tion taken on the line 3-3 of Figure 1;

Figure 3 is a detail section taken on the line 3-3 of Figure 1, with the displaceable or bendable part of one of the bearing portions being suggested in open position in dotted lines;

Figure 4 is a detail section taken on the line 4 4 of Figure 1, and showing the socket in place therein; and,

Figure 5 is a plan view of the blank used in manufacturing the handle socket.

Referring specically to the drawing, wherein like reference characters designate like or similar members, I!) indicates a mop head, for instance, generally of heart shape, which is usually stamped in one piece from sheet metal or any equivalent.

The head I has at the rear, a central depressed saddle portion II, at the forward extremity of which a concave bearing portion I2 is provided. At the rear of the saddle II, the head Ill is open or slotted, as at I3.

Compl'emental convex bearing portions I4 and yI are struck out from the head I0 on opposite sides of the bearing portion I2. One of such bearing portions, namely, that at i5, is severed from the head along an'angular path It, to provide a displaceable part Il, which is bendable to and from the full arid dotted line positions of Figure 3. Aside `from the bendable portion I1, the mop head I corresponds in structure and function to that disclosed in my aforesaid Patent 1,912,632, the head carrying thrums as suggested by the dotted lines in Figure 2.

The socket, according to the present ini/enf tion, is shown at I9. Such socket is preferably stamped in one piece from sheet metal, and, for instance, the same sheet metal as the head I0. The blank from which the socket is formed is disclosed in Figure 5, the same having lateral Wings a. adapted to be curled or curved in opposite directions to form a clamp 20 which receives the mop handle, the latter being securely fastened, as by means of a clamp bolt (not shown) passed through openings 2|. Forwardly of the clamp 20, the socket includes a neck 22 and in the blank form has lateral pintle portions b, each of which beyond the sides of the neck has extensions c. The socket across'the distal terminal of the neck and including the pintle portions b and their extensions c is curled to form the pintle 23 having extensions 24. It will be noted that the portions 24 are completely cylindrical since the portions b and c meet when curled, while the portion of the pintle 23 need not be curled to the extent of 360.

The unitary socket and pintle produced as described is applied to the head I0 when the part I'I is displaced or bent back to the dotted line position suggested in Figure 3. When the head Ill is in such condition, one of the pintle portions 24 is entered beneath the bearing I4 and the remainder of the pintle is received inthe bearing portions I2 and It, following which the part II is bent or restored to normal bearing condition and shape, as shown in the full lines in Figures 1 to 4. Thus, the socket and head are pivotally connected together and the disadvantages mentioned with respect to the structure of my patent are overcome.

As in my patent construction, the clamp is accommodated in the opening I3 and the angularity thereof is controlled by the shape of the neck 22, which contacts the saddle I E at the lower extrem ity of its movement.

The structure particularly enables manufacture of the mop head Without employing separate pintles which are usually of steel and the supply of which, especially under present conditions, is less plentiful than that of the sheet metal used in the manufacture of the head and socket, aside from the expense and other disadvantages attending their use. Y

Various changes may be resorted to within the spirit and scope of the invention as dened by appended claims.

What is claimed is:

l. In combination, a head comprising a plate having an open struck-out bearing portion and complemental struck-out bearing portions between which the open bearing portion is disposed, a unitary socket and pintle, the pintle including portions journaled in the complemental bearing portions, and one of the complemental bearing portions being displaceable on a line approximately parallel to the longitudinal axis of the pintle to expose the interior thereof to enable unitary application and mounting 0f the pintle with the socket on the head, said pintle being integral with the socket and having peripheral surfaces of approximately 360 Within the complemental bearing portions.

v2. In combination, a head having an open bearing portion and complemental bearing portions between which the open bearing portion is disposed, a unitary socket and pintle, the pintle including portions journaled in the .complemental bearing portions, and one of the complemental bearing portions having a part displaceable to expose the interior thereof to enable unitary application and mounting of the pintle with the socket on the head, said socket having portions extending laterally on opposite sides thereof, said socket across and including said portions being curled and forming the aforesaid pintle.

3. In combination, a head having an open bearing portion and complemental bearing portions between which the open bearing portion is disposed, a unitary socket and pintle, the pintle including portions journaled in the complemental bearing portions, and one of the complemental bearing portions being displaceable on a line approximately parallel to the longitudinal axis of Y the pintle to expose the interior thereof to enable unitary application and mountingof the pintle with the socket on the head, said socket having portions extending laterally on opposite sides thereof, said socket across and including said portions being curled and forming the aforesaid pintle, said portions on opposite sides of the socket having extensions which in the curled condition of the pintle render such portions of greater circumferential extent than the portions therebetween.

4. A handle socket having portions extending on opposite sides thereof, said socket across said portions being curled into a pintle adapted to be journaled in a head, said portions having ex-y tensions adjacent opposite ends extending longitudinally of the socket, to provide a pintle of greater circumference at its ends than at the portion of the pintle between said ends.
